Iwis drive systems introduces b.dry maintenance-free stainless-steel chains. The corrosion-free chains run completely dry, are extremely wear-resistant and withstand high dynamic loads. They are also maintenance-free and do not need any form of lubrication. These characteristics make them predestined for use in aggressive environments, for applications in which water or steam are applied or where strict cleaning regulations apply, such as the food and pharmaceuticals industries, in cleanrooms and in painting lines.

 

The new b.dry precision chains are suitable wherever relubrication is undesirable or not possible. They are hygienic and run completely dry: Thanks to the high-performance plastic friction bearings in their links, they need no lubrication of any kind, which also eliminates the need for relubrication. Made from a high-performance polymer, the sleeves are heavy-duty, low-friction and FDA-compliant. Contact with foodstuffs or hygiene products is safe. The stainless-steel bushes are thin-walled, seamless and ball-drifted. The CF base chain is made from austenitic stainless steel, making it highly resistant to aggressive media. The wear life of the b.dry chains is significantly long. They can be used in a temperature range from -100 to +200°C. They are also available as roller chains with attachments or extended pins. Custom-developed chains and ANSI chains are also available on request.
